It is the sheet material made from thin layers of wood
veneer glued together. To increase the wearability and durability of the
composite material, they keep the grains of the adjacent layers rotated by as
much as 90 degrees to each other. It belongs to the family of engineered wood
products of which includes hardboard particle board, and medium density fiberboard.
Made for a purpose
The method of manufacture of the plywood makes them
resilient and suitable for many purposes. For instance cross-graining helps
reduce the tendency of the plywood’s to split when nailed at the edges. It
improves the dimensional stability of the product and brings down the expansion
and shrinkage. The strength of the wood in all direction remains consistent.
All this happens due to the alternation of the grain when they bind the wood fiber
sheets with resin.
Depending on the choice of the wood material and the
method of manufacture, we have a variety of plywoods in use today. They include
the following:
· Tropical
· Softwood
· Flexible
· Aircraft
· Marine
· Hardwood
The number of piles of wood veneers in the plywood
remains odd because this helps reduce the warping. The high quality products
have the intervening veneers placed at 45 and 90 degrees so that they attain
high strength along multiple axes.
Use in moist and wet conditions
Often one needs it that performs well in humid and moist
situations. In this case, we choose durable face and core veneers. These resist
the delaminating forces and fungal attacks. By virtue of its construction, you
can use these Marine
Plywood for a long time in places
where one has plenty of moisture.
They fashion the wood veneers from tropical hardwoods
with negligible core gap. This limits the amount of water that gets trapped
within the plywood. Due to this, the glue bond in the plywood is stable and
strong. This exterior wood uses the exterior Water and Boil Proof glue.
